VALVE.

SPECIFICATION forming part of Letters Patent No. 477,392, dated June 21,1892. Application tiled July 27, 1891l Serial NOAOOQOO. (No model.)

T all whom t may concern.-

.Be it known that I, ADOLPH WEBER, a citizen of the United States,residing at Detroit, 1n the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Valves, of which thefollowing is a specification, reference being had therein to theaccompanying drawings. This invention relates to new and usefulimprovements in valves; and it consists in the peculiar construction ofa so--called angle-valve, and especially in the construction of thevalve-plug' thereof, all as more fully hereinafter described.

In the drawings, Figure l is a vertical central section through thevalve embodying my invention. Fig. 2 is a like section showing theValve-plug in closed position. Fig.3 is a horizontal section on line a'x in Fig..l. Fig. 1.1, is a detached perspective view of the plug.

A is a' cylindrical casing having the inletopening B and theexit-opening C at substantially right angles to each other.

D is a screw-cap secured upon thevalvecasing and provided with astuffing-box E.

F is the valve-stem passing through the stuffing-box, and. G is thevalve-plug. The valve-plug is provided on top with a nipple H, which isprovided with a cylindrical socket H', into which the lower end of thevalve-- stem partly projects, pressing against a small coil-spring I,housed in the lower portion of the socket, and adapted by its pressureto seat the conical enlargement J, formed on the valve-stem, into acqrresponding conical seat J', formed in the under side of the cap ofthe valve. The valve-stem is provided at its lower end with two lateralprojections form ed by a transverse pin K or otherwise, which engageinto the vertical guide-slots L, formed in the nipple. In the bottom ofthe socket H is a small hole H2, which communicates into the hollowinterior of the plug.

The Valve-plug consists of a circular disk forming the plug and asegmental cylindrical flange depending from the under side thereof andforming the body of the valve-plug, the lateral opening of which isadapted to register with the exit-opening in the valve-casing. Thediameter of the body of the plug is smaller than that of the top,thereby forming an annular rim M around the top, which engages upon anannular shoulder M', formed on the inside of the valve-casing to supportthe valveplug in position free to be turned, the tension of the spring Iholding it to its seat. The segmental cylindrical flange or body of theplug is approximately crescent -shaped in cross-section-that is, theopen ends or wings thereof are made tapering-and, furthermore, they aresevered from the top of the plug by saw-kerfs N. Before inserting theplug into the valve-casing these wings are sprung outwardly to a slightextent, as shown in dotted lines in Fig. 3, so that when the plug is inposition in the valve the tendency of the wings is to press against thewalls of the casing. This not only makes the wings tit tightly againstthe walls of the casing, but the whole plug, on account of the latterbeing more than one-half of a circle, so that the pressure of the wings,which is especially exerted on the free endspcrowds the back of the plugagainst the casing as Well. The plug thereby adjusts itself against thevalve-casing and makes the valve close steam and water tight. A lug O isformed on the lower edgen of the body of the plug, and this, inconnection with a segmental circular Iiange or stop P in the inner wallof the casing, limits the movement of the plug to one-half of a circlecorresponding to the open and closed positions of the valve.

In Fig. l the valve is shown in open position, which allows the fluidentering at B an unobstructed water-way through the hollow plug to theexit C, and as communication is afforded through the opening I-I2 to thetop of the latter it is fully balanced. By giving the stem a half-turnthe valve is closed, the turning of the plug being effected by theengagenient of the projecting ends of the pin K into the guide-slots Lof the nipple.

My improved construction of valve has the advantage that it takes littlepower to open and close it, that it is not apt to stick, and that it canbe readily repaired, if it becomes leaky, by expanding the wings of theplug, as described.

My valve is especially adapted for a radiator-valve, as leakage aroundthe stem is absolutely prevented even if the stuing-box should not bequite tight, as the conical en- IOO largement J on the stem is foritself adapted, if properly fitted, to form a tight joint. I am awarethat this feature of my valve is not broadlynew; but I have found thatin all constructions ot valves in which a spring is interposed betweenthe valve-stem and the top of the plug the spring is always liable toexert its pressure unevenly, and thus tend to produce an uneven wear ofthe parts. To prevent this, I interpose the spring directly between thelower housing, which prevents its displacement, in connection with aprojection on the end of the valve-stem,whieh pro-v jects into the eyeof the coil-spring, and in addition I project the stem into the housingof the spring, so that the parts are all maintained in the same axialrelation to each other.

I have not herein broadly claimed the combination of a cylindrical plughaving a perforated cap with side fianges, the cap for the Valve, theloosely-fitting stem, and an interposed spring, as I have made the samethe subject-matter of a concurrently pending application filed November28, 1890, Serial No. 372,940.

What I claim as my invention is- I. The combination, with thecylindrical valve-casing and screw-cap through which the valve-steinpasses, of a substantially cylindrical valve-plug provided with anannular rim around vthe top ot' the plug, the annular shoulder formed onthe casing, upon which said rim is seated, the nipple formed in thecenter of the valve-plug and projecting upwardly into the cap of thevalve-casing, the socket formed in said nipple, the coil-spring housedin the lower end of said socket, and the valve-stem projecting into thetop of said socket, substantially as described.

2. The combination, with the cylindrical valve-Casin g and screw-capthrough which the valve-stem passes, of a substantially cylindricalvalve-plug provided with an annular rim around the top of the plug, theannular shoulder formed on the casing, upon which said rim is seated,the nipple formed in the center ot' the valve-plug and projectingupwardly into the cap of the valve-casing, the socket formed in saidnipple, the coil-spring housed in the lower end of said socket, thevalve-stem projecting into the top of said socket, the conicalenlargement formed on the valve-stem, and the corresponding conical seatformed in the cap of the valve, substantially as described.

3. As a new article of manufacture, a radiator angle-valve consisting ofthe valve-casing A, having inlets and outlets B C, the screwcap D,having stuffing-box E and conical valve-seat J', the valve-steinprovided with the conical enlargement J, the valve-plug G, having thesegmental cylindrical body of crescent-shaped cross-section and thediskshaped'top of larger diameter to form an annular rim around theplug, the saw-kerfs N, severing the end wings of the body from the topof the plug, the annular shoulder M on the valve-casing, the nipple H onthe valveplug, forming-a cylindrical housing, the spring I, housed insaid nipple, the valve-stem projecting into said nipple and providedwith the transverse pin K, the guide-slots L in said nipple, the lug O,depending from the valveplug, and the segmental flange or stop P on thevalve-casing, all combined and operated substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.

ADOLPH IVEBER.
